Recently, we have developed sensors capable of ground-based, round-the-clock observation of faint airglow and auroral emissions, highly sensitive EUV/FUV spectral imagers (one currently flying aboard the ISS) and a full-waveform lidar for imaging trees in forests. These activities have led to one of our current projects to directly image exoplanetary environments.

Scot R Elkington University of Colorado Laboratory for Atmospheric and Space Physics Boulder, CO My research has focused on techniques leading to a quantitative physical understanding of energetic particle dynamics in the inner magnetosphere and central plasma sheet during geomagnetically active periods. Central to this study is the use of the Lyon-Fedder-Mobarry MHD code to model magnetospheric configuration in response to both real and idealized solar wind conditions. Analytical magnetospheric field models are also used, where necessary, to examine relevant physical processes under simplified conditions. Finally, observational data are used both as a tool for providing realistic initial conditions within the models, and for verifying the validity of the simulations. The fundamental intent of this work is to gain a better physical understanding of the processes playing roles in storm-time radiation belt dynamics. However, all work is undertaken with an eye toward fitting these approaches within the larger framework of a global magnetospheric circulation model, and providing valid predictive tools for space weather forecasting.

Justin C. Kasper University of Michigan Atmospheric, Oceanic and Space Sciences Ann Arbor, MA Justin designs sensors for spacecraft that explore extreme environments in space from the surface of the Sun to the outer edges of the solar system. He is interested in understanding the forces that lead to solar flares and the solar wind, a stream of particles heated to millions of degrees in the Sun's atmosphere, or corona. His major results concern heating, instabilities, and helium in the solar corona and solar wind, and the impact of space weather on society. In 2007, he used measurements by the Voyager spacecraft to detect the termination shock, a massive shockwave surrounding our solar system. He has served on advisory committees for NASA, the National Science Foundation, and the National Academy of Sciences. He currently leads the SWEAP Investigation, an international team of scientists and engineers building sensors that will collect samples of the Sun for the NASA Solar Probe Plus spacecraft, a mission of exploration that will make history in 2018 as the first human-made object to plunge into the solar corona.
Dr. Namir E. Kassim Naval Research Laboratory Remote Sensing Division Washington, DC Physical processes falling under the rubric of the Sun-Earth connection, particularly those that can be studied at radio wavelengths, including a strong interest in understanding the corona, CMEs, and the ionosphere/plasmasphere. A current thrust is the measurement of Faraday Rotation against polarized sources to constrain CME magnetic fields. A recent tool is our VLITE (http://vlite.nrao.edu) system on the Jansky Very Large Array. Our group has started a new program to identify recent geomagnetic storm events and evaluate corresponding VLITE observations during those events. VLITE can detect Total Electron Content (TEC) fluctuations much more accurately than GPS, making it a powerful tool with which to study ionospheric/plasmaspheric disturbances and turbulence associated with solar-induced geomagnetic storms. While our group is primarily radio astronomers, we work closely with scientists in the Solar Physics Branch within our sister Space Sciences Division at NRL.

Prof. Jonathan J Makela University of Illinois Electrical and Computer Engineering Urbana, IL My research interests lie in multi-technique remote sensing of the Earth's ionosphere. He works with ground- and satellite-based instrumentation to study both the quiet-time and storm-time behavior of this region at low- and mid-latitudes. To accomplish this, he develops, tests and deploys suites of sensors to sites around the world. These instruments include portable imaging systems, Global Positioning System (GPS) receivers, and Fabry-Perot interferometers. My research group is currently working on developing new techniques and algorithms to simultaneously analyze these multiple datasets to better understand the underlying electrodynamics of instability processes in the equatorial and mid-latitude ionosphere. These instabilities can cause problems for satellite navigation and communication signals that have to propagate through them. Understanding how and when they develop will lead to more robust systems.

Eberhard Moebius UNH Space Science Center & Physics Department Durham, NH My research interest is centered on the acceleration of particles in and their transport through the heliosphere with the help of composition sensing ion and neutral atom sensors. Using pickup ions in the solar wind (SOHO, ACE, and STEREO) and energetic neutral atoms that originate in the interstellar gas and in the heliospheric boundary regions (IBEX), we are studying the inflow of interstellar gas into the solar system, its interaction with the solar wind, and further acceleration of its products to higher energy. With these tools we scope out the outermost shield of the Earth against cosmic rays and lay the groundwork to understanding short and long time variations of the heliosphere. In addition, interstellar and inner source pickup ions form a suprathermal particle population that serves as an effective source for the generation of energetic particles at interplanetary shocks, which contribute significantly to the energetic particle environment of the Earth.

Richard M Thorne UCLA Atmospheric and Oceanic Sciences Los Angeles, CA My primary research interest is the dynamic variability of the radiation belts, with emphasis on the role of wave-particle interactions. Waves in the magnetosphere of the Earth and Jupiter can cause pitch angle scattering and loss of trapped particles to the atmosphere, and also local stochastic energy diffusion. My group at UCLA is currently studying such processes using data from the Van Allen probes at Earth and JUNO at Jupiter.
Steven Tomczyk Tomczyk High Altitude Observatory Boulder, CO My research interests include: 1) development of instrumentation for the observation of magnetic and velocity fields in the solar atmosphere, with an emphasis on the solar corona. 2) analysis of coronal wave observations to infer the magnetic field through coronal seismology 3) analysis of the polarization of coronal emission lines to infer the geometry and strength of coronal magnetic fields. The ultimate goal of my research is to understand the buildup and release of magnetic energy in the solar corona that can cause disturbances in the near-Earth environment known as Space Weather.

Dong L Wu NASA GSFC Greenbelt, MD Impacts of solar forcing and variability on Earth's atmosphere and climate. Uses of satellite data (MLS, SORCE, AIRS, GPS, AMSU/SSU) and model simulations (WACCM, GISS) to identify, characterize and understand Sun-Earth connection processes. Dr. Dong L. Wu is a research scientist at NASA's Goddard Space Flight Center (GSFC). His research interests include remote sensing of atmospheric dynamics and clouds, and sun-climate connection. For the sun-climate connection studies, his research has been focusing on impacts of the 11-year and 27-day variations in solar forcing on the upper and middle atmospheric dynamics and chemistry. The data analyses include uses of satellite measurements from Aura/MLS, Odin/SMR, TIMED/SABER, and GPS radio occultation, MERRA reanalysis, and simulations from WACCM.
